The Rich/Poor Ratio as a Measure of Inequality in the 2020 Distribution
The 2020 global income distribution chart introduces the rich/poor ratio as a measure of a country's internal inequality. This ratio is calculated by comparing the income of the wealthiest 10% of the population (represented by the height of the back bar) to that of the poorest 10% (the height of the front bar).

The Rich/Poor Ratio as a Measure of Inequality in the 2020 Distribution
Comparing National Income Inequality
In a hypothetical country, the average annual income for the wealthiest 10% of the population is $240,000, while the average annual income for the poorest 10% of the population is $12,000. Based on this information, what is the country's rich/poor ratio?
Consider a country where the rich/poor ratio, defined as the average income of the richest 10% divided by the average income of the poorest 10%, is currently 15. A new government policy is implemented that results in a 5% increase in the average income of the poorest 10% of the population, while the average income of the richest 10% remains unchanged. What will be the effect on the country's rich/poor ratio?
Country A and Country B both have a rich/poor ratio of 10. In Country A, the average income for the richest 10% of the population is $100,000 and for the poorest 10% is $10,000. In Country B, the average income for the richest 10% is $50,000 and for the poorest 10% is $5,000. Based solely on this information, which of the following statements is the most accurate conclusion?
True or False: A decrease in a country's rich/poor ratio, which compares the average income of the richest 10% to the poorest 10%, definitively indicates that the economic well-being of the poorest 10% has improved.
Limitations of the Rich/Poor Ratio
Critiquing the Rich/Poor Ratio as an Inequality Metric
An economic analyst is evaluating different policy outcomes to reduce a country's rich/poor ratio, which is defined as the average income of the richest 10% of the population divided by the average income of the poorest 10%. Which of the following scenarios would cause the largest decrease in this specific ratio?
Evaluating a Policy Metric
An economic report for a country states that its rich/poor ratio, defined as the average income of the richest 10% of the population divided by the average income of the poorest 10%, has increased over the past year. Which of the following scenarios is the only one that could explain this change?

Examples of the Rich/Poor Ratio from the 2020 Distribution
Analyzing Internal Income Inequality
Consider two hypothetical countries. In Country A, the average annual income for the richest 10% of the population is $100,000, and for the poorest 10% it is $5,000. In Country B, the average annual income for the richest 10% is $40,000, and for the poorest 10% it is $1,000. Based on the ratio of the richest 10% income to the poorest 10% income as a measure of internal inequality, which statement is accurate?
Evaluating the Rich/Poor Ratio as an Inequality Metric
Country A has a rich/poor ratio of 40, while Country B has a rich/poor ratio of 20. This information alone is sufficient to conclude that the wealthiest 10% of the population in Country A have a higher average income than the wealthiest 10% in Country B.
Calculating and Interpreting Income Inequality
You are given the rich/poor ratio for four different countries. This ratio compares the average income of the wealthiest 10% of the population to that of the poorest 10%. Match each country with the most accurate description of its internal income inequality based on its ratio.
A country implements a new economic policy that results in a 15% increase in the average income for the poorest 10% of its population. During the same period, the average income for the wealthiest 10% of the population remains unchanged. How would this change affect the country's rich/poor ratio, which is used as a measure of internal income inequality?
In a specific country, the average annual income for the wealthiest 10% of the population is $150,000. If the country's rich/poor ratio, a measure of internal inequality calculated by comparing the income of the wealthiest 10% to the poorest 10%, is 30, then the average annual income for the poorest 10% of the population is $____.
Imagine a chart that visualizes a country's internal income inequality by showing the average annual income for its wealthiest 10% of citizens as a tall back bar and the average for its poorest 10% as a shorter front bar. The ratio of the back bar's height to the front bar's height is used as the measure of inequality.
- For Country A, the back bar is 50 units high and the front bar is 1 unit high.
- For Country B, the back bar is 100 units high and the front bar is 10 units high.
Based on an
A country experiences a decade of strong economic growth. Despite this, a report shows that its rich/poor ratio, which compares the average income of the wealthiest 10% to that of the poorest 10%, has worsened, increasing from 20 to 50. Which of the following statements provides the most accurate analysis of this situation?
